non-prophet group
Any organization or gathering of realistically-practical and open-mindedly compassionate people who are genuinely trying to assist their fellow humans with specific problems, and who wish to do so in a sane rational truly-effective "real world" manner, without trying to force a huge load of prejudiced acridly-critical theological "tough love" babble down the throats of the unfortunates who are seeking their help.
I hate it when non-prophet groups are labelled as "heathen" or "atheist" --- heck, they're just trying to actually provide people with what they really need, but without being destructively judgemental... what's so horrid or "sinful" about that???
